[PATCH] remoteproc: imx_rproc: Use strstarts for "rsc-table" check

Posted by Shenwei Wang 1 week, 3 days ago

The resource name may include an address suffix, for example:
rsc-table@1fff8000.

To handle such cases, use strstarts() instead of strcmp() when checking
for "rsc-table".

Before applying this patch, I want to know how it ever worked before.  How
did DT with a suffix tested?
